What Are Progressive Slots and How Do They Work?

You will usually see a section of an online casino library that is dedicated to jackpot games or progressive slot machines. These games are similar to normal slots in a lot of ways. However, the main difference is that a portion of every qualifying bet that you place on one of the markets will contribute to an ever-growing jackpot. This jackpot will keep expanding until someone wins it and then it will reset once more.

Usually, this massive jackpot will be one at random when playing the game or when you successfully complete a bonus game. The top prizes on offer can sometimes surpass ten million pounds, so there is big money up for grabs off relatively low stakes, similar to what you would find with a traditional lottery.

In order to qualify to be in with a chance of winning the progressive jackpot, you will normally need to play at the maximum bet. Other smaller stakes may not qualify you. Sometimes, you will win the jackpot randomly when playing the game, while you may earn the jackpot if you hit certain symbol winning combinations. There are also some jackpots that are must-win by a certain date.

Oftentimes, the progressive jackpot will be shared across the entire network rather than being specific to a certain online casino. This means that everyone across the world who is playing that specific title will be contributing to the jackpot.

Are the chances of winning progressive jackpot smaller vs the standard slots?

One of the best ways to gauge the possible return from playing any casino game is by looking at the return to player (RTP) percentage for a given title. This represents how much you can expect to get returned to you when you play a certain game. For normal video slot machines, the RTPs will generally lie between 96% and 97%.

The RTPs of progressive jackpot slots will usually be lower because a portion of your bet in a lot of cases will be adding to the jackpot. However, the standard gameplay if you are not contributing to the progressive jackpot will be similar to if you were playing a standard video slot.

With the progressive jackpot, you are able to be in with a chance of transforming a small bet into a large win. However, there are big odds of winning. For example, the popular Mega Moolah progressive slot has a 50 million to one chance of being won. However, there is always a chance for players to get their hands on this jackpot, adding to the overall excitement of the playing experience.
